Abstract

Patients with Fabry disease undergoing enzyme replacement therapy showed stabilization of left ventricular mass and native T1 mapping, whereas the extent of late gadolinium enhancement slightly increased.

Purpose

To perform a systematic review and meta-analysis to assess the effect of enzyme replacement therapy on cardiac MRI parameters in patients with Fabry disease.

Materials and Methods

A systematic literature search was conducted from January 1, 2000, through January 1, 2024, in PubMed, ClinicalTrials.gov, Embase, and Cochrane Library databases. Study outcomes were changes in the following parameters: (a) left ventricular wall mass (LVM), measured in grams; (b) LVM indexed to body mass index, measured in grams per meters squared; (c) maximum left ventricular wall thickness (MLVWT), measured in millimeters; (d) late gadolinium enhancement (LGE) extent, measured in percentage of LVM; and (e) native T1 mapping, measured in milliseconds. A random-effects meta-analysis of the pooled mean differences between baseline and follow-up parameters was conducted. The study protocol was registered in PROSPERO (CRD42022336223).

Results

The final analysis included 11 studies of a total of 445 patients with Fabry disease (mean age ± SD, 41 years ± 11; 277 male, 168 female). Between baseline and follow-up cardiac MRI, the following did not change: T1 mapping (mean difference, 6 msec [95% CI: −2, 15]; two studies, 70 patients, I2 = 88%) and LVM indexed (mean difference, −1 g/m2 [95% CI: −6, 3]; four studies, 290 patients, I2 = 81%). The following measures minimally decreased: LVM (mean difference, −18 g [95% CI: −33, −3]; seven studies, 107 patients, I2 = 96%) and MLVWT (mean difference, −1 mm [95% CI: −2, −0.02]; six studies, 151 patients, I2 = 90%). LGE extent increased (mean difference, 1% [95% CI: 1, 1]; three studies, 114 patients, I2 = 85%).

Conclusion

In patients with Fabry disease, enzyme replacement therapy was associated with stabilization of LVM, MLVWT, and T1 mapping values, whereas LGE extent mildly increased.
